Add dashboard job keyword search and fix listings scroll alignment

Wire search submission to filter mock listings by whitespace-separated
tokens (case-insensitive). Show empty-state copy when nothing matches,
return full catalog for empty query, and handle Return in the keywords
field. Use a flipped document view so short result lists sit under the
search bar without a large gap. Tweak mock job description wording.
